2. Standardized ileal amino acid digestibility of plant-based feedstuffs and phytase supplementation in broiler chicken diets
RESUMO Objetivou-se determinar a digestibilidade ileal estandardizada dos aminoácidos (SIAAD) do farelo de soja (FS), milho + FS, trigo + FS e uma dieta livre de proteína (PFD) com fitase. Um total de 672 pintos machos (493±10g), Cobb 500, foi distribuído em um delineamento inteiramente ao acaso, com 12 tratamentos (PFD, PFD + FS, PFD + milho + FS e PFD

3. Does environmental enrichment improve performance, morphometry, yield and weight of broiler parts at different ages?
RESUMO A inclusão do enriquecimento ambiental na criação convencional dos frangos de corte pode causar aumento na mobilidade, massa óssea e músculos. O objetivo desta pesquisa foi avaliar o uso do enriquecimento ambiental na criação de frangos de corte em diferentes idades e sua influencia no desempenho, morfometria, rendimento e peso das partes. Foi

4. Intestinal morphometry and performance of broiler chickens subjected to diets with buriti oil
RESUMO Objetivou-se, com essa pesquisa, avaliar o desempenho produtivo, o rendimento de carcaça e a morfometria intestinal de frangos de corte com dietas submetidas à inclusão do óleo de buriti. Trata-se de um alimento energético que pode ser utilizado na alimentação de frangos visando substituir o óleo de soja, o qual apresenta alto custo na produç

5. Isolation and molecular characterization of Campylobacter jejuni from chicken and human stool samples in Egypt
Abstract Two hundred broiler chicken samples, 160 laying chicken samples and 75 human stool samples were collected in Egypt. The samples were microbiologically examined, and the C. jejuni isolates were confirmed biochemically and by PCR targeting the mapA gene of C. jejuni. The prevalence of the cadF virulence gene was then determined using PCR. A total of 1

6. COMPUTATIONAL ANALYSIS OF LOAD VENTILATION IN BROILER TRANSPORT
ABSTRACT The characterization of ventilation during the transport of broiler chickens is essential for identifying and characterizing the potential problems of a convective heat flow and its effects on the welfare and the health and production conditions of the chickens. The objective of this study was to evaluate the ventilation patterns in two layout model

7. CHARACTERIZATION OF THE THERMAL ENVIRONMENT IN BROILER HOUSES WITH DIFFERENT CLIMATE CONTROL SYSTEMS
ABSTRACT The environment control of broiler houses must be done adequately to provide good thermal conditions to broilers without wasting energy. The objective of this study was to characterize the thermal environment in two mechanically ventilated broiler houses with a negative pressure ventilation system, one with a cellulose pad evaporative cooling system

9. COMPOSTING PROCESS IN THE PRODUCTION OF LETTUCE SEEDLING SUBSTRATES: EFFECT OF COVERING AND TURNING FREQUENCY
ABSTRACT The composting of waste from a broiler chicken production chain (BCPC) promotes the mitigation of environmental impacts and allows the commercialization of compost as an agricultural input. Both the characteristics and the potential for use of the final compost depends on the operational conditions during composting. The objective of this study was

12. Características do trato digestivo, metabolizabilidade e retenção de nutrientes em frangos de corte alimentados com complexo enzimático
ABSTRACT The objective was to evaluate the digestive tract characteristics, metabolizability and nutrient retention of broilers fed diets supplemented with enzyme complex (EC). To evaluate the characteristics of the digestive tract 600 female Cobb 500 birds were used, distributed in a completely randomized design, with 5 inclusion levels of the EC (0; 100, 2
